P4 Diagnostix

What P4 Diagnostix does

P4 Diagnostix, operating through its parent entity Theranostix, Inc., is a privately held network of clinical, anatomical, and molecular diagnostic laboratories headquartered in Beltsville, Maryland. The company markets itself as a nationally recognized network of state-of-the-art labs serving reference laboratories, long-term care facilities, ambulatory surgery centers (ASCs), and physician group practices across Connecticut, Maryland, New Jersey, New York, Texas, and Virginia. Its service model is consultative and B2B, with a sales-led go-to-market targeting specialty practices in urology, gastroenterology, respiratory care, women's health, dermatology/podiatry, and long-term care, supported by a national mobile phlebotomy network.

The company's product portfolio combines a proprietary branded molecular test line with cloud-based healthcare IT. Branded molecular assays include UTiD (urinary tract infection panel detecting 30 pathogens and 24 antibiotic resistance genes), GPiD (gastrointestinal pathogen PCR panel with 99% NPV), RPiD+ (respiratory pathogen PCR panel covering SARS-CoV-2, Influenza A/B, and RSV), WPiD (wound pathogen panel with 95% sensitivity/specificity and antibiotic resistance gene detection), a Nail PCR Pathogen Panel (29 pathogens, 99% accuracy), and Barrett's FISH for esophageal monitoring. Underpinning these is the VitalAxis cloud-based healthcare IT platform, which delivers electronic ordering, reporting, EMR connectivity, and Vital Office Connectivity to more than 10,000 physicians (including over 5,000 urologists) and more than 100,000 end users with zero upfront investment. Digital pathology services complement the lab offerings by enabling remote slide access and collaborative review.

P4 Diagnostix generates revenue through fee-for-service laboratory testing billed to healthcare providers and their patients, with no publicly disclosed pricing. The network was assembled through the consolidation of several regional labs (Theranostix, Platinum Pathology, Long Island Pathology, P4 Clinical/Manhattan Labs, Connecticut Pathology Laboratories) under the P4 Diagnostix umbrella, with subsequent inorganic expansion including the February 2020 acquisition of Strand Diagnostics. Strategic partnerships with VitalAxis (healthcare IT), Vital Logistics (specimen logistics), P4 Physicians, and Superb Diagnostics (nail pathogen assay co-development) extend the company's reach. The company is HIPAA-compliant and operates with 101-250 employees across multiple physical lab sites; revenue is not publicly disclosed.
